Methods and systems for deploying seismic devices

A system for taking acoustic measurements relating to subterranean formations, comprising:

• at least one acoustic tool to acquire the acoustic measurements, the at least one acoustic tool comprising a spring-actuated locking arm located on an outside of a tool housing;
• a conveyance configured for movement of the acoustic tool in a borehole traversing the subterranean formations;
• a tool retainer configured or designed for permanent deployment in the borehole to removably retain the tool in the borehole so that the acoustic tool is deployed at a predetermined location and orientation relative to the subterranean formations, the tool retainer comprising a groove located on an inner surface of a borehole casing joint;
• a computer in communication with the acoustic tool;
• and
• a set of instructions executable by the computer that, when executed:
• process the acoustic measurements;
• and
• derive parameters relating to the formation based on the acoustic measurements, wherein said at least one acoustic tool is adapted to be remotely activated to place the tool in a state to form a connection with the tool retainer by extending the spring-actuated locking arm into the groove;
• wherein the acoustic tool further comprises:
• a support arm located on an outside of the tool housing;
• and
• a clamping pad, wherein the clamping pad is supported by at least one of the spring-actuated locking arm and the support arm, and the clamping pad is configured or designed to fit within the groove of the tool retainer.
